Features

• Add, delete, update, and view todo tasks.
• Dockerized deployment for easy portability and scalability.
• CI/CD pipeline for automated testing and deployment.
• Integration with Jenkins for CI automation.
• Deployment automation through ArgoCD and Kubernetes.

Prerequisites

Ensure you have the following installed:

• Docker
• Jenkins
• ArgoCD
• Kubernetes (minikube or any Kubernetes cluster)

Installation

1. Clone this repository:

    git clone https://github.com/ARUP-G/Python-todoApp-Jenkins-Argocd-K8s.git

2. Navigate to the project directory:

    cd Python-todoApp-Jenkins-Argocd-K8s

3. Build the Docker image:

    dokcer build -t todo-app:1 .

Run

Docker way

1. Run the Docker container:

    docker run -d -p 5000:5000 todo-app:1

2. Access the Todo app through your web browser at http://localhost:5000.

CI/CD Pipeline

The CI/CD pipeline for this project is orchestrated using Jenkins, ArgoCD, and Kubernetes.

1. Continuous Integration (CI) with Jenkins: Upon pushing changes to the repository, Jenkins automatically triggers a build job. This job involves running unit tests and linting to ensure code quality.

   • Jenkins: Build jenkins pipeline and build and run the pipeline.

2. Continuous Deployment (CD) with ArgoCD and Kubernetes: Once the code passes CI, Jenkins triggers a deployment job. This job builds a Docker image and pushes it to a Docker registry. ArgoCD, configured to monitor the repository, detects changes and automatically deploys the updated Docker image to the Kubernetes cluster.

• Push to Docker Hub: By executing the pipeline the image will be added to dockerhub registry.

Note: Make sure to change "Push the artifacts" stage in jenkinsfile with proper credentials and registry username.

• ArgoCD: Go into deployment manifest module and execute the command.

   kubectl apply -f service.yaml

  *For more information about the deployment manifest visit https://github.com/ARUP-G/Todo-app-deployment-manifest.git

To access the app

• Minikube way

  minikube service todo-service

  then you will get the url to access the app.
